The Super 4
Looking back at my time at Tiger there was a lot going on with the 3 wheeler, but at the same time it was the birth of the "Super 4". When I got there in late 85' I was use to going out and riding a lot on Powroll's mile long MX track and half mile TT track, at Tiger there was only one place to ride and that was inside the shop at night after everyone was gone. I would move things off to the side and make a track inside. The pics only show about half the shops length, I could get in 3rd gear pretty good, just wasn't room for error! Peter had built a wooden ramp just like the Mickey Thompson track had so I could dial in the Super 4 and 3 Wheeler's FOX Shocks. In the late summer months I would open the shop doors after 30min. of riding because I would start get sloppy after breathing in the the 2 stoke race gas (LOL), but then the mosquitoes would be so thick on the lights it would get dark inside. Yeah the land of 10,000 lakes also had a bazillion mosquitoes! And in the dead of winter you couldn't only ride the 30min. and could only leave the doors open a little while before you froze, it just wasn't the best conditions for training, but I made due.
> The Super for was more like a Suzuki Quad Racer in front. I didn't know anything about setting up a front end, so the guy that designed it gave us two choices, make it so it had long travel with some bump steer, meaning as you went through the travel the toe in would go in and out to a degree. Or it could have wash, meaning the toe in would stay the same and as it went through the travel it would just get wide, that sounded the best to me, but just like the Suzuki it wasn't as good as Honda's FourTrax design where the tipped the a-arms back and had the best of both set ups. It was great for TT but as we seen over the years Honda was the best on MX.
> I only got to try and race it at the Mickey Thompson race in Pontiac Mich. I felt good in practice, the ramps were the same so I had it working pretty good. The first heat went bad in the first corner when someone rear ended me and it took out about four of us in a chain reaction. I ended up under the nerph bars and couldn't get out from underneath the quad, and once the flipped it off me I found we had broke a tie rod. Being the one and only Super 4 we had no spare parts and I was out just like that! Having never raced a quad before even if we would have had spare parts I wouldn't have know what to bring, it is what it was.
> At this point the only time I really got to ride was inside the shop and at the track, but the only tracks now were ice races. I only raced once for Honda on the ice and that didn't go good. I won one race but only because Daryl Rath gave me some much needed tires. New York Ice racing was nice compared to Minnesota ice, I had to sit in the van the whole day and start the 3 wheeler 15. min. before the race and let it idle to get it warm enough to race, not fun. My hat is off to people that live in the mid west and go racing all the time, but it wasn't for me! See less

In my short time at Tiger the bikes changed a lot. We got a lot done, the biggest and best changes came while I was there.
Time to get to work!
The thing that was cool about working at Tiger is I didn't have to deal with bean counters, and we weren't waiting on the OK from upper management to make changes. In fact after the first time I raced one I showed Peter what changes needed changed, and he had most of it done before I got moved back there, like only weeks from that race. The new front forks with shorter bottom legs were already in production to get the front end down with more travel. The back sub frame was changed to get the rear of the seat higher so you didn't wear out pulling yourself forwards all the time. Also change the rear end for more travel which helped from bottoming the bottom of the frame into the ground, but that part of the frame never got change to give more ground clearance it still needed. The next thing for sales purposes was to update the looks with a new short course looking tank like the 85' Honda 250r I raced had, and the change to two rads for better cooling and looks along with a nicer looking front fender. The rake of the forks still needed to come in a few degrees so he built a adjustable front rake to test where the production bikes would be.
Things happen real quick, and the motor was next. Because these motors were also used in cart racing you could change every gear in the gear box, we had side mount carbs and two different cylinders, one with the exhaust port in the rear kind of like the new Yamaha 4 strokes have and a power valve on the front ex. port. My problem was I had never messed with a Rotary valve motor so I sent JP Racing a 200 to build and Selvy got a 250 I think. So much happen in a short time my memory isn't the best and we had so much going on. We even got a Rotax 350cc 4 stroke in that was shorter to fit in the 3 wheeler/ quad frame and it was few pounds liter then their 500cc. That went to Powroll to be bored and stroked as big as they could.
The things that could have happen.
I had never put a whole machine together myself, I didn't know how heavy the front hub was, the rear hubs, the hubs that held the rear disk and sprocket, and the swing arm. All these should have been made of aluminum. Maybe the rear swing arm could have been built like the triple clamps.
Now all my old machines and a lot more are sitting in a collection worth about a half million in Virginia a Binky's. See less

Was contacted by another Tiger 200 owner in NY that wants me to buy his 200. He won't send pics because he doesn't want it all over the internet and he only wants to deal with me. I don't know if it's the one I raced or not, don't even know what to look for to tell for sure or not unless it has the number plate still on it. So I'll take another road trip and check it out.

I love it when people think out side the box.

If you didn't see this kid race South Wick this past weekend you missed something never seen before. He won the 250 class first moto by over 30 sec. Then while winning the second moto he crashed hard and broke his collar bone, BUT he kept racing and got back in first and won by another 15 sec. Who does that?

It's taking a lot longer for my fabricator to build my 1988 ThreeTrax 200x Works aluminum gas tank with 86' 250r scoops , but I think it's going to be awesome! 350x next.
